Sharpen
The trading journal that tells you why you lose
Log a trade or a bet in 30 seconds, or import your broker / sportsbook CSV. Sharpen computes your real numbers — expectancy, profit factor, drawdown — and finds the behaviors that cost you money: tilt, revenge sizing, bad hours, unplanned entries. Each leak comes with the proof, in dollars. Weekly review by DM. Free for 30 entries a month, Pro $19/mo, runs on Whop.
Hi Product Hunt, I'm Lucas, maker of Sharpen.
I journaled my trades in a spreadsheet for two years and the only thing it ever told me was my P&L. What actually cost me money was invisible: the entries I took 20 minutes after two losses, the size that doubled after a red day, the 15:30–16:30 block where I never win.
Sharpen finds those patterns in your own data and prices them. Log a trade or a bet in 30 seconds, or import any broker / sportsbook CSV. You get your real numbers (expectancy, profit factor, drawdown), the 10 "money leaks" with the proof in dollars, discipline rules that flag every violation, and a weekly review by DM.
It runs on Whop (billing + community), free for 30 entries a month, Pro is $19/month.
Two free tools if you don't want an account: an expectancy calculator that also prices your tilt entries (https://sharpen-six.vercel.app/t...) and a 12-column CSV journal template (https://sharpen-six.vercel.app/t...).
Tell me which leak detector you'd add — I'll build the most requested one.
